Bursting Disks for Tank Container

Serie(n): SF
Typ(en): SF-M-TB / SF-MD-TB

STRIKO tank bursting disks protect tank containers and tank wagons against impermissible overpressure and/or underpressure. The flat tank bursting disk is available in the versions SF-M-TB (vacuum-supported and with PTFE protective film on the product side) and SF-MD-TB (double-acting). STRIKO tank bursting disks are used to transport gases, liquids or multiphase media safely on our roads and tracks. A flanged centering collar allows reliable installation and centering of the rupture disc between two flanges (fail-safe installation). Tank bursting discs for common bursting pressures are available from stock in nominal sizes DN 65 and DN 80, offering you the greatest possible flexibility and rapid availability.
